Abstract: NRAO, with the assistance of engineers and astronomers from the Naval Research Laboratory (NRL), has installed a 74 MHz receiver and removable dipole on the Pie Town VLBA antenna (Pt). First fringes with this system represent another major milestone for low-frequency radio astronomy by extending to the already unprecedented baseline length of >50 km. The importance of the link for scientific observations is the 2X improvement in angular resolution for sources with declinations north of about +40 degrees (12 arcseconds at 74 MHz), while maintaining the full sensitivity of the VLA (about 50 mJy/beam for a full track at 74 MHz).
